 Clang build is made by http://hg.mozilla.org/mozilla-central/file/tip/build/unix/build-clang/build-clang.py script. You may want to use this script to discover the recent used version of clang.
+= Compilation =
+MacOS X builders have everything installed to build clang.
+Linux64 (Centos 6.2) needs the following packages installed:
+ yum install make gcc gcc-c++ mercurial subversion patch \
+  http://puppetagain.pub.build.mozilla.org/data/repos/yum/releng/public/CentOS/6/x86_64/gcc472_0moz1-4.7.2-0moz1.x86_64.rpm \

+Linux32 (Centos 6.2) needs the following packages installed:
+ yum install make gcc gcc-c++ mercurial subversion patch \
+   http://puppetagain.pub.build.mozilla.org/data/repos/yum/releng/public/CentOS/6/i386/gcc472_0moz1-4.7.2-0moz1.i686.rpm \
+   http://puppetagain.pub.build.mozilla.org/data/repos/yum/releng/public/CentOS/6/i386/mozilla-python27-2.7.3-0.el6.src.rpm
+To build clang clone mozilla-central and run the build script:
+ hg clone https://hg.mozilla.org/mozilla-central
+ cd mozilla-central/build/unix/build-clang
+ # adjust revision in build-clang.py if needed
+ time /tools/python27/bin/python2.7 build-clang.py # go and drink something
+Once the build is finished you can find 2 not tracked files (hg st) in the current directory. <tt>clang.manifest</tt> should be attached to the bug and $SHA512 should be uploaded to the tooltool server (see below).
